A tabulation of observed absorption maxima is made and an interpretation of the spectra provided. This is based on symmetry changes on the nitrate group, resulting from changes in the metal-to-nitrate bond. The compounds are classified as to the degree of ionic or covalent character.", pages = "59-70", url = "http://www.ingentaconnect.com/content/sas/sas/1959/00000013/00000003/art00002", doi = "doi:10.1366/000370259774614960" }
